I'm not hostile to Great Cthulhu's ideas at all, infact I think it would be great to have done. I'm just pointing out that there's no reason or excuse to wait for Toady to approve anything. That's just a waste of time that could be better spent doing all the work involved. No "official" sanction required.
So many great ideas and projects that might really improve things for everyone, inevitably fall into the "we need officialness!" trap. In the "real world", there might be legal issues, so in that case it's understandable to be concerned, but in this case-in the environment provided by Toady-the percieved "need" for permission is illusionary. Yes, there might possibly exist a certain amount of security in the thought that Toady would now be aware of such a project-essentially "overseeing" it, and able to update the rest of the game around it-but that just puts the burden of *your* project on Toady's shoulders. He'd become responsible for it, which is unnecessary, and not very fair.
As far as using the "officialness" of the project to attract volunteers to it, again, that's putting the burden of the work on other people. And it's not like you can't still request volunteers for projects, without official sanction. I've proven that that works.
I'm not intending this to sound aggressive, but if you want to do the work, do the work. Put up or shut up, in other words.
